High-end Tunnel Formwork

Q:For example, lining, invert, bias and so on words,, to answer the full thank you: Bias: refers to the formation of the tunnel, resulting in uneven pressure. To provide you with a few books you go to see the explanation. The site is easy to understand.

Q:What are the driving jobs in the tunnel: Outside control traverse 2) elevation control survey 3) in construction traverse

Q:When the tunnel fight, there is no provision to fight how many meters left, only by one of the construction: Fixed strip: the use of additional reinforcement fixation; special fixture fixed; the wire and the fixed template (Figure 2).

Q:The tunnel has the super big pipe shed and the lead small conduit, is carries on the blasting excavation first or carries on the advance support first, has the anchor rod in the tunnel, this between the construction craft order is any: Measuring and setting out the drill hole charge blasting, ventilation, smoke exhaust, water spraying and dust removing, the top of the vertical arch, the anchor rod and the reinforcing steel net, the spraying concrete operation enters the next cycle, and the first branch is stabilized and then the two lining is applied

Q:12 meters of the tunnel car, under normal circumstances, one of the two months to be able to cast a few models?: Seven hours after the maintenance of formwork, pouring a every day is no problem, that is to say a month to about fifteen die casting.

Q:Main diseases and prevention of tunnel: Tunnel shotcretePhenomenon: the concrete spray layer and the rock surface is not bonded, concrete spray layer between the bond is not good.Cause analysis: the loose rock not clear spray surface; shotcreted rock debris is not scum washing or flushing thoroughly with wind pressure, water pressure; surface by spraying water, water, water concentration of untreated concrete spraying interval; before a layer of spray surface without wind, water washing scum. The air pressure is inconsistent with the spray distance.Preventive measures: remove the loose rock, clear surface by spraying of water, slag floating debris; water, concentrated water point of the surface by spraying with gouge, guide the drainage treatment of buried pipe; sprayed concrete before spray test, to determine the wind and spray distance coordination relationship between.

Q:Would you please tell me the difference between the concrete and shotcrete in the tunnel?: These two kinds of concrete construction method is actually the difference.Formwork concrete: after the formwork is good, the concrete is the concrete, such as the tunnel lining, the bridge pier and so on.
